Application filed August 13, 1921. Serial no. 491,964.

To all who-12bit may concern:

Be it known that I, JosEPH H. ARnNns, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in an Automatic Stop and'Replaying Device, of which the following is a specification.

My invention relates to a combined automatic stop and replaying device for phon graphs and has for its particular object the combination of a device which can be used as an automatic stop when the playing of a record has been completed, or which will automatically transfer the sound box and tone arm back to the starting point on the record and play the record over again as many times as may be desired.

Another and further object of my invention is the provision of areplaying device which canbe set so as to play a record an indeterminate number of times or which can be so set that the record will be played a predetermined number of times and when the operation. is completed a brake will be automatically applied to the turn-table of the phonograph and its operation stopped.

Another and further object of my invention is the provision of a replaying apparatus which provides a minimum load upon the motor of the phonographand which requires only a small force to operate it and also in which there is no side thrust upon the shaft leading from the turn-table to the motor, as is the case with the phonograph replaying apparatus which have been here tofore designed.

Another and-further object of the invention is the provision of a replaying' apparatus whichis simple in operation and which (an be easily adjusted to play a record of any size, or which can be dispensed with entirely and the phonograph operated in the usual manner.

These and other objects of my invention will he more fully and better understood by reference to the accompanying sheets of drawings, in which- Figure 1 is a plan view of my improved invention Figure 2 is a vertical sectional view of the bracket to which the repeater bar is secured;

Figure 3 is a vertical end view of the bracketsho'wn in Figure 2;

Figure 4- is a detailed "view in elevation of the tone arm and bracket along the line 4-t of Figure 1; and

Figure 5 is a side elevational view of the base of thetone arm and the stop for actuating the device.

Referring now specifically to the drawii'igs, and in which like referencecharacters refer to like parts throughout, a phonograph cabinet is shown having a motor board 11 secured thereto in the usual manner.

IL turn-table 12 is provided having a down-' wardly' turned flange 13 thereon against which the brake is applied ashereinafter described. A ring member 14 is provided which is secured to the motor board 11 by means of screws 15 which pass through the base or flange portion of the member 14 and which rests securely against the motor board 11-. A tone arm 17 is mounted within the member 14: in the usual manner, and is curved upward and towards the forward portion of the phonograph and. over the turn-table in the usual manner and'has a sound box secured thereto at its outer end in the usual manner common to phonographs. The turn-table 12 is mounted upon a motor shaft 18 which leads to the motor and which may be either the usual type of spring motor or electric motor with which phonographs are frequently provided. cured to the shaft 18 is a gear wheel 19 which is positioned below the turn-table upon which the record rests while being played. A second gear wheel 20 is provided which is secured to themotor board by means of a screw 21, the gear wheel 20 hav-' ing a smaller gear wheel 22 secured thereto or integrally therewith, as may be desired, the gear wheel 20 being in mesh with the wheel 19 and at all times is rotated whenever the phonograph is being played. draw bar 23 is provided which is pivotally secured to a power bar as also pivot-ally mounted to the motor board 11 by means of a screw 25, a pin 26 serving to connect the bars 23 and 24: together. Secured to the power bar 24 is a gear wheel 27,the wheel 27 having an offset portion 28 and being normally out of engagement with the small gear wheel 22' except when the tone arm is being transferred to the outer part of the rec- 0rd, as hereinafter described. The power bar 24 is-connected to the wheel 27 by means of a pin 29 at one side of the center of said wheel so that as the wheel 27 is rotated the powerbar 24: will be given a reciprocatory movement, as hereinafter described. A member is secured to the motor board by means of screws 31 and having a ver tically looped portion 32 which extends above the motor board 11 and has the end of the bar23 inserted between the portions of the looped member 30 so that the said member forms a guideway for the end of the bar 23 as it is moved backward and forward. Mounted within the loop 32 of the member 30 is a crank member 33 having a downwardly extending portion 3st which is inserted into an opening 35 in the end of the draw bar 23. Secured to the member 33 is a repeater bar 36 by means of a pin 37 or in any other approved manner and which is adapted to be tilted upward by the draw bar 23 during the operation of the device. Secured to the end of the bar 36 is a small pin 38 which projects down- 'wardly and has a spring 39 secured thereto and which is secured to a pin 40 in the wall of the loop 32, the purpose of this spring being to hold the repeater bar to one side of the turn-table and out of the way of removal of a record if the replaying de vice is not being used.

It will be understood that the repeater bar 36 extends across the face of the turn-table l2 and underneath the sound box and is tilted upward by the action of the lever 23 as hereinafter described,- so that the sound box slides along the repeater bar 36 toward the outer edge of the record until it is caught by a stop 41 adjustably secured to the repeater bar. by means of a screw 42 so that the outward movement of the sound box is stopped at the proper position to insure the sound box needle being positioned into the outer sound groove of the record. A clip 43 is secured to the base of the tone arm 16 by means of screws 44 and has an outwardly projecting lug 45 to which a clip 46 is secured by means of a pin 47. Mounted within the clip 46 is a crank member 18 having a downwardly projecting pin 49 secured thereto and a button 50 on the outer end thereof so that the device may be easily set, as desired. The member 48 is held in the frictional engagement of its sides with the clip 46 so that the position of the pin 49 may he changed to any desired position to cam-e the brake to be applied to the turntable or operate the repeating apparatus. as hereinafter described.

Secured to the motor board 11 by means of a screw 51 is a V-shaped lever 52 having a projection on its ends adjacent the draw bar 23 and which engages against the shoulder 5aformed on the draw bar 23 and which serves to normally hold the gear wheel 27 out of engagement with the gear wheel A clip 55 is secured to the motor board having a set screw therein and against which the lever 52 abuts when o ieratedlrv is a lever 58 which is secured to the motor board 11 by means of a screw 59, the screw 59 passing through a fan shaped member 60 which turns upon the screw 59 and which forms a regulator for the operation of the device. An arm 61 integral with the member 60 is provided in the end of which a button 62 is inserted having a pointer 63 positioned in the end thereof for the purpose of indicating the proper position of the arm 61. The member 60 in its marginal edge has a; deep recess 64 therein and has in its periphery on each side of the recess 64: notches 65 and 66. A brake member 67 is provided which is secured to the motor board by means of a screw 68 and has an L-shaped end 69 with a roller 70 mounted in the end thereof which is adapted to seat in the recess 64 or in any of the notches 66 during the operation of the device. A yielding brake element 71 is secured to the brake member 67 and which is adapted to contact with the flange 13 on the turn-table 12 when the brake is in position to stop the operation of the machine. Secured to the end of the member 67 is a spring 72 which is fastened to the motor board 11 by means of a screw 73 the member 67 also having a rod 74 secured thereto, the opposite end of which is adapted when the brake is set in the machine to fit into a notch 75 on the side of the draw bar 23, thus serving to lock the draw bar 73 until the rod 74 is pulled out of the notch 75 by the action of the member 60 when it is turned and set in any desired position; A clip 76 is secured to the rod 74 and a spring 77 secured thereto which in turn is fastened to the arm 58 and serves to pull the arm 58 against the pin 86, thus pulling the catch 83 out of the notches 65. The hole in the bar 58 through which the pin 57 passes is su'tficiently large to allow a slight movement of the arm 53. A spring 73 is secured. to the end of the arm 52 in a notch 79, the opposite end. of the spring lH- ing secured to a notch 80 .in the draw bar 23 and this spring also assists in pulling. the driving wheel 27into engagement with the small pinion 22. An indiiuitor plate 31 is provided which is secured to the motor board by means of screws 32. 32. and over which the handle 61 of the indicator (it) extends. The plate 81 has iuarli'ings thereon to indicate the various positions of the arm 61 in the set of the device such as Repeat only at one end thereof, Automatic stop at the other end. and in between these points from 1 to 5, indicating the number of times a record can be played until the brake will be applied to the machine. In the posi- "tion shown in the drawings the brake is applied to the turn-table 12 and the turntable therefore held against rotation. A catch 83 is secured to the member 58 by means of a pin 84 and has a spring 85 mountedthereon which is adapted to push the member 83 downward into engagement with the notches on the marginal edge of the member (30. A pin 86 is inserted in the motor board and contacts with the upper end of the member 83 so that in the position of the device shown in the drawings the device 88 will not engage in the notches G5 on the edge of the device 60, but is held above the edges of the notches 65 so that the device can be turned freely about the member Immediately upon the arm :38 being pushed back the member 83 will be pushed downinto contact with the member (50 and engage the notches 65 until the arm 58 is pulled into the position shown in the drawings when the device 83 willabut against the pin 86, thus lifting the end 83 out of the notches.

In the operation of the device the tone arm having the sound box mounted on the end thereof is grasped by the operator and moved until the needle of the sound box is over the outer groove of the record and "the stop 41 on the repeater bar 36 set in the proper position so that the sound box will be placed in contact with the record at the outer sound groove of the record. The tone arm is thereupon pushed to the innermost sound'groo-ve of the record and the stop 48 set in proper position -for the pin L9 to engage the. end of the lever 52 so that when the sound box plays to the last sound groove the pin 4-9 will engage against the end of the lever 52 and pull the end 53 of the lever 52 over the shoulder 54 in the draw bar 23 and allowing the wheel 2'? to come into mesh with the small wheel 22.

in the operation of the device, as shown in the drawings the brake member 67 is engaged in. the recess 6st of the member 60 and the device is in locked position. If it is desired to set the machine so that it will constantly repeat, the player grasps the button 62 on the end of the lever 61 and turns the device around to the point Repeat only on the indicator 81.. The turning of the member 60 to this position releases the brake Tl against the turn-table 12 and allows the roller to become seated in the lowermost notch 66 in the member 60 and also holds the rod H out of the recess 7-5 in the draw bar 23, thereupon the phonograph starts to play and the soundbox following the grooves on the record until the innermost groove is reached, whereupon the tone arm has been turned until the pin 4:?) contacts with the. end of the lever 52 which raises the opposite end of the lever 52 out (it the notch 64 and allows the spring 78 to pull the driving wheel 2? into engage ment with the wheel 22 which starts to rotate and cause a reciprocatory movement to the draw bar 23 through the action of the member 24 which is secured to the Wheel 27. As the member 23 reciprocates the crank 33 is turned and lifts the repeater bar 86, the outer end of the repeater bar being tilted upward so that "the sound box slides along the repeater bar until it contacts with the stop 42 whereupon the repeater bar is held down in the position shown in Figure 2, whereupon the sound box contacts with the record, the needle in the sound box is seated in the outer groove and the device commences playing the record over again. The member 83 on the bar 58, during the operation just described, is positioned on the marginal edge ofthemember '60 imn'iediately adjacent the recess 6a and does not engage in any of the notches 65 so that the device set in this position will continue to play as long as power is supplied through the motor. If it is desired to play a recordsay five times, the bar 61 is pulled around to the figure 5 on the repeater bar, whereupon the :roller 7 0 will be engaged in the second notch 66 on the marginal edge of the member 60, and when the operation described above takes place at the time the record is played the member 8, owing to the movement of the lever '58, will engage in one of the notches 65 and will automatically turn the handle 61 back-to 4 on the indicator and as the device continues playing each time the record is played the device 60 is rotated one point until the po sition of Auto-stop is reached on the indicator and after record has been played with the arm in this position the brake is applied to the turn-table, thus effectively stopping the operation of the turn-table. As the member 60 is turned so that the roller 70 is in the lowermost notch 66, the member 83 contacts with the smooth outer periphery of the member 60 adjacent the notch 6a, so that this member 83 does not engage in one of the notches 65 when the device operates to return the tone arm to the outer side definite number of times or it can be re-' peated any number of times up to and in cluding 5, and the device may also be used simply as abrake by setting the arm 61at the position of Auto-stop on the indicator, whereupon the record Will be played once and the brake applied after the record has been played. It will also be understood that the arm 36 e'an b'e turned around along-- Hil side of the turn-table as a pivotal movement is permitted upon the pin 37, so that if it is desired to operate the machine by hand and use the device as a hand brake the machine can be played and controlled by hand operation in the usual manner.
